JavaScript Object Notation (JSON) is a lightweight data-interchange format. It is easy for humans to read and write. It has a data format that is inter-changeable with a programming languages built-in data structures that eliminates translation time and reduces complexity and processing time. Moreover, JSON has the same strengths of XML. Therefore, it's better to shift form XML security to JSON security. In this paper, we will present how to shift from XML encryption to JSON encryption. © 2014 IEEE.
